To `ALL WHOM 1T MAY CONOERN: y.

'Be it known that I, J. H. DOUTHIT, of Albany, Linn county, '0regon,^bave invented anew and improved will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specication,`in which- Figure 1 is a planv or top view 4of my `invention, partly in section.

Figure 2, aside sectional view of the same, taken in the line :1: x, tig. 3.

Figure 3, a transverse vertical section of the same, taken in the line y y, fig.' 2.

Similar letters of reference indicate like parts.

This invention relates to a new and improved gang plough, and it consists in a novel construction and arrangement of parts, as hereinafter fully shown and described, whereby the operator has full or perfect control over the ploughs.

A A represent twoparallel bars, connected at oneend by cross-bars B B, and having an axle, C, bolted to their upper sides. D D are the wheels on said` axle, and E is'a draught-pole, securedbetween the cross-bars B'B. F F represent two parallel plough beams connected by cross-bars a, 'and having each a plough, G, attached, one a little in advance of the other. The front cross-bar, a, of the plough beams F F, has its ends extending through the beams FF, and is fitted in slides H H, the latter working between suitable guides,

ing forward so that its-'front end maybe readily acted upon by the foot of the driver from his seat J, for the purpose of elevating, when necessary, `the front ends oi' the plough beams; and the other slide, or both, in fact,

desired height, and consequently regulate the depth of the penetration of the ploughs asl may be desired. The drivers seat, J, is secured to parallel horizontal bars, d d, supported by uprights, e e, from the bars A A. L is a windlass, the bearings of which are in the'bars-d d. This windlass has a cord or chain, M, attached, which is connected to the outer cross-bar, a, of the plough beams F F, and to one end of the shaft vof windlass L a crank, N, is attached, and a ratchet, O, also keyed upon it, intoV which ratchet a pawl, P, catches. To the windlass, L, there-is also attached a cord or chain, M', which is Wound around the shaft of the windlass in an opposite direction to the cord or chain M, and passes around a pulley,f, in -the rear end of a bar, Q, secured inthe framing of the machine, andthen passing upward is attached to a cross-bar,.a, of the plough beams. '.l'his cond or chain, ll serves to keep the ploughs G Gein the ground, as it holds the plough beams FF down and as said cord or chain is wound upon the windlass L, in a reverse direction to the chain M, it will be seen that when the windlass L is turnedin a direction to wind the chain M upon it, the` chain M will be unwound from it, and 'vice ocrsa.. Hence it will be seen that by turning the windlass L, the ploughs may be elevated ont. of the ground when not required to operate, and be lowered| intothe ground when required for use, without being in the least interfered with by the chain M. The windlass L is designed to be turned by hand, and is used only when the ploughs are elevatedpcrnianentlyas, for instance, in drawing the device from place to place. The ploughs are raised temporarily by means of a windlass, R, one end of which has its bearing-attached to one of the bars d, the other end having its bearing in a slide, S, to which a lever, T, is attached. On this windlass shaft, at the outer side of the slide S, thereY is 'keyed a pulley, U, having a ratchet V attached ,to its inner side, and. around the pulley U and apulley' W attachedtoone of' the wheels, D, a belt L passes. X is a pawl which engages with 'the ratchet V, and has 'a spring, z', :lering upon it to keep it in contact with the ratchet V, and a lever, Y, attached to it for the purpose of .throwing the pawl outl or oil` from the ratchet when necessary, (sec lig. 2.) TheA belt L is to betiglitened at any time by actuating the leverT, so as vto rotate the windlass R, and raise the plough beams F F. Through the medium of a cord orchain A*, rendered slack by releasing the ot' the uindlass R. Y

From the above description it will be seen that the ploughs are under the complete control ofthe operator or driver, and may bercadily operated or manipulated by bini. The draught-pole may be shifted laterally between the bars B B, according, to the direction Ot' theline of draught required,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. vThe attaching of the plough beams F F to slides H H, fitted between suitable guides c e, at the innex` sides of the bars A A, in connection with the foot-lever I, attached to one of the slides H, and the pin K'pnssing through any of a. series of holes in the other slide H, substantially as and fox-the purpose set forth.

2. The windlass L, having' the cords or chains M M attached, :md Ythe latter connected to the plough beams F'F, to operate in the manner substantially as and`for the purpose specified.

3. The Windlass R, having a,- cord or chain A* attached, which is connected to the plough beams F F 5 one of the bearings of the windlass being fitted in s slide S, and having a. pulley U on one end, around which and a pulley W, on wheel D, a belt L passes, in combination with the lever T attached to slide S, all being arranged to operate in the manner substantially as and for the purpose set forth. 1
